Faster `PauliwordOp.to_opemnfermion` #175

Closed MIWdlB closed 7 months ago

MIWdlB commented 7 months ago

Previous version of the function used symplectic_to_string then looped through the string.

I've made a new function which amends symplectic_to_string directly so that this isn't necessary.

symmer/operators/base.py

Looks like a huge amount of change but its mostly linting (suggests that CICD is not working as intended). I can revert that if you'd rather.

Can probably be made a bit faster by converting the whole symplectic in a vectorised function but low priority to figure that out.
